Detailed Description

One Update of cooked orbit input.

Bindings stay in the app.

Read GLFW / ImGui in the app, then fill this. orbit tumbles around COrbitDrive::target. pan is truck + pedestal (slide target on the view plane). With viewH set, pan tracks the screen so DPI and zoom stay natural; otherwise it uses a radius heuristic. dolly / wheel zoom: perspective dollies radius; orthographic scales CCamera::orthoHeight and leaves radius as the clip standoff. wheel applies when blocked. blocked clears an in-progress drag (gizmo, UI, off-bed). With havePivot, orbit tumbles about pivot (captured at press) and wheel zoom anchors on it, so the content under the cursor keeps its screen position.

Member Data Documentation

viewW

float rig::OrbitNavFrame::viewW = 0.f

Viewport size in the same units as mouseX / mouseY (GLFW pixels).

When viewH > 1, pan matches on-screen motion at the orbit target (FOV / ortho height); otherwise falls back to a radius heuristic.
